Description

Es gibt Unterläufermahlgänge, bei denen der Oberstein durch Federn gegen den Unterläuferstein gepreßt wird. Wenn bei diesen Gängen der Oberstein infolge eines auftretenden Widerstands nach einer Seite ausweichen muß, so erhält die auf der anderen Seite befindliche Feder eine stärkere Spannung und übt an dieser Stelle einen stärkeren Mahldruck aus. Gleichzeitig wird die Feder auf der entgegengesetzten Stelle entspannt, und der Mahldruck an dieser Stelle läßt nach. Der Mahldruck zwischen zwei Mühlsteinen muß aber immer möglichst der gleiche bleiben und darf nicht ständig wechseln, weil sonst völlig ungleiche Mahlergebnisse erzielt werden. Die Arbeit der Federn sollte dreierlei bewirken: erstens den Oberstein in der Drehrichtung elastisch halten, zweitens dem Oberstein seitliche oder exzentrische Ausweichungen ge-There are Unterlaufer grindings in which the Oberstein is pushed against the Unterlauferstein by springs is pressed. If the Oberstein dodges to one side as a result of resistance during these courses must, the spring on the other side receives a stronger tension and exerts a stronger grinding pressure at this point. At the same time the spring opens the opposite point relaxes, and the grinding pressure at this point decreases. Of the The grinding pressure between two millstones must, however, always remain the same as possible and must not change constantly, otherwise completely unequal grinding results will be achieved. the The work of the springs should do three things: first, the top stone in the direction of rotation hold elastic, secondly the Oberstein lateral or eccentric deviations

so statten und drittens dem Oberstein ein axiales Ausweichen ermöglichen. Diese Wirkungen können aber, wie vorstehend geschildert, nie ohne gegenseitige schädliche Beeinflussung untereinander auftreten.so, and thirdly, equip the Oberstein with an axial one Allow evasion. However, as described above, these effects can never occur without mutually damaging influence on one another.

a5 Durch die Erfindung werden deshalb die drei bezweckten Wirkungen jede für sich erreicht, indem in Kombination der Oberstein gegen Drehung durch elastische Anschläge, gegen zu große seitliche oder exzentrische Ausweichungen durch Puffer gesichert und zum Zweck eines axialen Ausweichens durch eine elastische Andrückvorrichtung gehalten wird.a5 The invention therefore the three intended effects each achieved for itself by combining the Oberstein against rotation by elastic stops, against too large lateral or eccentric ones Evasions secured by buffers and for the purpose of an axial evasion an elastic pressing device is held.

Die Abb. 1 und 3 zeigen eine solche An-Ordnung. Die elastischen Anschläge ^"halten den Oberstein gegen Drehung zurück. Die elastischen Puffer ^.verhindern zu große seit- /. Q liehe Verschiebungen, und die elastische Andrückvorrichtung \ läßt axiales Ausweichen beim Eintritt unvermahlbarer Körper zu.Figs. 1 and 3 show such an arrangement. The elastic stoppers ^ "keep the upper stone against rotation back. The elastic buffers ^ .verhindern excessive lateral /. Liehe Q offsets, and the elastic pressing means \ allowed to axial deflection upon entry unvermahlbarer body.
